04d4ec9c57 pinctrl: at91: add option to use drive strength bits
SAM9X60 uses high and low drive strengths. To implement this, in
at91_pinctrl_mux_ops::set_drivestrength we need bit numbers of
drive strengths (1 for low, 2 for high), thus change the code to
allow the usage of drive strength bit numbers.

The pinctrl supports to set any bit in input register on iMX6 if
the MSB of input value is 0xff. But the driver uses signed int for
input value, so when executing the codes below, it won't meet.
Because this is arithmetic right shift.

b6a6238f04 Revert "dm: pinctrl: Prevent (re-)configuring pins when already done before relocation"
This reverts commit a7f4b4b344.

As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:

1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)

2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).

3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).

As we are very close to release - please revert this commit.

600888110d rockchip: rk3399: Add improved pinctrl driver.
The current pinctrl driver for the RK3399 has a range of qulity issues.
E.g. it only implements the .set_state_simple() callback, it
does not parse the available pinctrl information from the DTS
(instead uses hardcoded values), is not flexible enough to cover
devices without 'interrupt' field in the DTS (e.g. PWM),
is not written generic enough to make code reusable among other
rockchip SoCs...

This patch addresses these issues by reimplementing the whole driver
from scratch using the .set_state() callback.
The new implementation covers all featurese of the old code
(i.e. it supports pinmuxing and pullup/pulldown configuration).

This patch has been tested on a RK3399-Q7 SoM (Puma).

a7f4b4b344 dm: pinctrl: Prevent (re-)configuring pins when already done before relocation
This commit prevents from re-configuring pins if those were configured
before relocation.

Some pins - like UART or DDR must be setup before relocation
(as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this
change, those pins are re-configured after relocation (pre_reloc_only = 0,
so we do not "continue").
Such behavior may be a problem for DDR PAD configuration, as they might
be already leveled/tuned with original setup).

01aa9d1d54 pinctrl: MediaTek: add pinctrl driver for MT7629 SoC
This patch adds pinctrl support for MT7629 SoC. The IO core found on
the SoC has the registers for pinctrl, pinconf and gpio mixed up in
the same register range.  Hence the driver also implements the gpio
functionality through UCLASS_GPIO.

This also creates a common file as there might be other chips that use
the same binding and driver, then being a little more abstract could
help in the long run.

Add get_pins_count ops to obtain the number of pins
owns by a pin-controller.
On STM32 SoCs bindings, each pin-controller owns
several gpio banks. Each GPIO bank can own up to 16 pins.

To obtain the total pins count, walk through each sub-nodes
(ie GPIO banks) and sum each GPIO banks pins number. For that
in probe() we build a list with each GPIO device reference found.
This list will also be used with future get_pin_muxing and get_pin_name
ops to speed up and optimize walk through all GPIO banks.

As this code is common to all STM32 SoCs, this code is put
under SPL_BUILD compilation flag to avoid to increase SPL code size
for STM32F7 which is limited to 32Ko.

ad0e804843 pinctrl: Remove DM_FLAG_PRE_RELOC flag in various drivers
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

23626cac4b arm64: a37xx: pinctrl: Fix the pin 23 on south bridge
Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.

Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.

The bug was visible when the gpio regulator used the gpio 23, the whole
rgmii group was setup to gpio which broke the Ethernet support on the
Armada 3720 DB board. Thanks to this patch, the UHS SD cards (which need
the vqmmc) _and_ the Ethernet work again.

On the south bridge we have pin from 0 to 29, so it gives 30 pins (and
not 29).

This adds support for the (to date unsupported) I2C controllers 1~4
and 6~7 (i.e. now all controllers except I2C5, which is not accessible
on the RK3399-Q7, are supported by pinctrl).

b08c8c4870 libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>
Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.

This commit moves the header code:
  include/libfdt.h         -> include/linux/libfdt.h
  include/libfdt_env.h     -> include/linux/libfdt_env.h

and replaces include directives:
  #include <libfdt.h>      -> #include <linux/libfdt.h>
  #include <libfdt_env.h>  -> #include <linux/libfdt_env.h>

9821636b64 bcm2835_pinctrl: Probe pre-reloc
The serial drivers now depend on the pinctrl driver to determine whether
they are enabled. That means if a serial device wants to be used pre-reloc,
we also need the pinctrl device pre-reloc.

Adapt the pinctrl driver as well as dts overlay accordingly.

caf2233b28 bcm283x: Add pinctrl driver
The bcm283x family of SoCs have a GPIO controller that also acts as
pinctrl controller.

This patch introduces a new pinctrl driver that can actually properly mux
devices into their device tree defined pin states and is now the primary
owner of the gpio device. The previous GPIO driver gets moved into a
subdevice of the pinctrl driver, bound to the same OF node.

That way whenever a device asks for pinctrl support, it gets it
automatically from the pinctrl driver and GPIO support is still available
in the normal command line phase.
